Being you did plugs and wires and then the problem started. I would say you broke the coolant sensor on the drivers side head or disconnected the plug on accident. Just taking a shot in the dark there, But I would go check.

My suggestion would be to have a thread title that makes sense.

i checked the plug that was my thought after some time i realized i may have hit the plug off. but as for damaging the plug how fragile are they i did not hit it i dont think.
